GALVANlC BATTERY.

SPECIFICATION armies pm of Letters Patent No. 705,616, dated July 29, 1902. Application filed December 1, 1900. Serial No. 88.286." (No mode 1.)

T0 aZZ whom, it may concern."

Be it known that I, CHARLES.B. SCHOEN- MEHL, a citizen of theUnit'edStates, and a resident of Waterbury, in the county of New Haven and State of Connecticut, have in- It is the object of my invention to produce,

an improved form of electric battery of the above type which is especiallyfdesigned for use in automobiles, locomobiles, or other selfpropelled vehicles, or, in fact, in'any place where they would be subjected to rough usage, such as shaking or jarring.

To accomplish the objects desired, I have produced a battery'the several parts of which are rigidly secured within its jarf The cover, which is also within the jar, is sealed down in position to prevent the shaking or splashing out of the solution contained therein.

With the above objects in view my invention resides and consists in the novel construction and combination of parts shown upon the accompanying sheet of drawings, forming a part of this specification, and upon which similar characters of reference denote like or corresponding parts throughout the several figures, and of which Figure 1 shows a central vertioallongitudinal section through a battery containing my improvements. Fig. 2 is a plan view of Fig. 1. "Fig. 3 shows a detached view of the parts used inand forming a part of my improved battery.

Referring in detail to the characters of reference marked upon the drawings, A indicates a battery-jar of the usual or any preferred construction or material. 13 represents a solution contained therein,whichmay also be of any of the preferred kinds, such as caustic soda. Oxid of copper C is retained within the pockets D, formed adjacent to the interior wall of the jar by means of the corrugated sheet-tin tube E, arranged against said jar, as shown in Figs. 1 and 2. Against thiscorrugated sheet-metal tube is placed a detachable perforated sheet-tin wall F, inclosingthe inner side of the inner pockets formed by the corrugated tube before mentioned. In practice both this corrugated tube and the plain inner perforated sheet-metal tube are formed in straight sections or strips and rolled up into a tube with their uniting ends loosely overlapping, as shown at G in Fig. 2, making them adjustable within the jar and also readily remov able when recharging or other occasion may require. The interior wall F is preferably provided with studsH, as shown in Figs. 1 and 2, toform rests upon which to support an eXpansible wire 1. (Shown in all three of the figures.) This wire is made of spring metal and in practice is bent substantially as'shown inFig. 3, and from this shape it is compressed by hand sufficiently to be placed interior of the walls in question'in a manner to force them out tightly against the jar, thus producing a perfectly rigid oXid-of-copper receptacle interiorof'th'e zinc, which operates in conjunction therewith. These, parts, togetherwith their inclosed ingredients, (oxid of copper,) comprise the negative element of my, battery, andagainst theinterior wall thereof I attach a post J ,close to the bottom, as shown in Figs. 1 and 2, which post isdefiected inward and brought upcentralof the basket,vwith its vupper end threadedyto receive;the jam-nuts K Kand the bindingfnut L, whichlatter secures the field-wire M.

Nrepresents a cover, which may be made of cork,:wood, rubber,or any suitable insulating material. a This in practice is preferably constructed as shown inFigrb-namely, with itsupper edgebeveled oif, as at O, and its lower edge formed of adiameter to snugly engage the interior of the jar. This cover, as will be seen, rests upon the upper. edgeof the perforated sheet-metal strips, and by reason of its engagement with the sides of. the jar is necessarily heldrigid. After the cover is placed in position, as shown in Fig. 1, I

pour around its edges andwithin the recess formed by the beveled-off portion melted wax P or similar material, so as to seal the jar and more rigidly bind the cover in position,

thus preventing the escape of the fluid.

The zinc element Q for the battery is located interior of the oXid of copper and is preferably of cylindrical form and supported from the cover before mentioned by means of wires T T, which are secured to the cover, similar to the central wire, with jam-nuts R B, one of them being provided with a binding-nut S for the attachment of the fieldwire.

A battery such as I have shown and described in this application fills arequirement which few, if any, batteries now upon the market have met to the full satisfaction of makers of gasolene or self-propelled vehicles, wherein electricity is resorted to for producing the spark to ignite the vapors employed to generate power, and since it is ex-. ceedingly simple in construction and likwise practical in operation it is thought to be especially desirable and that it will be met with great demand by the trade.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a battery of the class described, the combination with a jar, of perforated sheetmetal tubes located therein to form a receptacle for a depolarizer, an expansible wire interior of said part or parts adapted to force them outward and retain them rigidly against the jar, a Zinc located interior of said depolarizer and means for the attachment of a wire to each of said elements, substantially as shown and described.

2. The combination with a battery-jar, of an expansible corrugated sheet-metal tube arranged interior thereof, an expansible perforated sheet-metal tube interior of said corrugated tube and an expanding device interior of the inner tube to force both of said tubes outward against the jar to insure their snugly engaging the same and being retained in position, a depolarizer arran ed within the corrugations of the outer tube and a zinc central of said parts.

3 In a battery, the combination with a corrugated tube adapted to fit into a jar, of a perforated sheet-metal expansible tube inside of the corrugated tube and an expansible device interior of said inner tube adapted to force the same snugly against the corrugated tube.

4. The combination with a battery-jar, of an expansible tube located therein forming a pocket or pockets intermediate of it and the jar, an expanding device interior of the tube to insure its snugly impinging against the jar in a manner to prevent its displacement, substantially as described.

5. The combination with a jar, of an expansible tube interior thereof, a depolarizer intermediate of the tube and jar, an expanding device interior of the tube to force the latter outward against the depolarizer, and means for suitably inclosing and sealing the jar.

6. In a battery of the class described, the combination with the other parts of an annular depolarizer-receptacle having a detachable adjustable interior wall, an expansible wire ring adapted to fit against said adjustable wall in a manner to force the same outward, as, and for the purpose set forth.

7. The combination in a galvanic battery, of a negative element comprising a series of vertical pockets, an oXid-of-copper element within said pockets, connections therefrom for the field-wire, a positive element interior of the said negative element, a cover supported upon said negative element and supporting the positive element, and means for sealing the cover to the jar, substantially as shown and described.

Signed at Bridgeport, in the county of Fairfield and State of Connecticut, this 22d day of November, A. D. 1900.
